Description

Technical Field

[0001] The invention belongs to the technical field of seismic isolation bearings, and in particular relates to an auxiliary installation device and an installation method for a seismic damper. Background Art

[0002] Seismic dampers, also known as earthquake dampers, are devices used in building structures and bridges. Their main function is to reduce the vibration and displacement of the structure when an earthquake occurs, thereby protecting the structure from damage or reducing damage. Seismic dampers consume seismic energy and reduce the dynamic response of the structure by increasing the damping characteristics of the structure, and are widely used in building structures.

[0003] There are many installation forms for existing seismic dampers, such as a stable support structure for damper installation disclosed in the authorization announcement number CN218668002U, which is fixed by fixing the fixing rod to the wall, and then passing the limiting rod through the mounting block and the viscous damper in turn, and then installing the limiting plate on the limiting rod. When the limiting plate is installed on the limiting rod, the two sliding blocks are brought closer to each other by rotating the bidirectional threaded rod, and then the limiting plate is inserted into the limiting groove on the sliding block, and then the threaded column is turned into the threaded groove on the limiting plate. When the limiting plate is fixed, the connecting rod is loosened, and the connecting rod will be inserted into the sliding groove on the adjustment gear under the action of the compression spring elastic force, and then the other end of the limiting rod can be fixed. The above does not have a specific positioning and adjustment device, and there is an installation deviation, which is easy to reduce the stability of the damper after installation.

[0004] The Chinese application document with application publication number CN114508256A discloses a seismic damper installation and connection device, which includes a damper body, a hoisting device, a mounting seat and a traction device, two hoisting devices are symmetrically connected to the damper body, and the two ends of the damper body are symmetrically rotatably connected to the mounting seat. When the seismic damper and the connecting seat are connected by the above-mentioned seismic damper installation and connection device, repeated fine-tuning operations are required, thereby reducing the efficiency of the seismic damper installation.

[0005] A Chinese patent with the authorization announcement number CN208501952U discloses a shear-type metal damper installation structure, which includes a structural vertical member, a structural beam, a shear-type metal damper, a connection node, an installation space, a node connection rib, a damper pre-set anchor rib and a casting block. A group of structural beams are arranged between the structural vertical members, a group of structural beams are arranged with an installation space between adjacent ones, a shear-type metal damper is arranged in the installation space, a filling gap is arranged between the two ends of the shear-type metal damper and the structural beam, and a connection node is arranged at the two ends of the shear-type metal damper. The connection node is arranged at the filling gap position for connecting the shear-type metal damper to the structural beam. The above-mentioned installation structure needs to first connect the shear-type metal damper to the upper connection node. After the main structure is topped, the wall is built from the top layer downwards, and the shear-type metal damper is also connected to the lower connection node from the top layer downwards as the wall is built. This method is limited by the construction of the building structure, the installation environment is single and limited, and the efficiency is low.

[0006] The Chinese patent with the authorization announcement number CN218233873U discloses an installation structure for a building seismic connecting beam damper, which includes a bottom plate, a fixing plate arranged on the end wall of the bottom plate, a stabilizing device arranged on the end wall of the fixing plate, the fixing plate is connected to a square frame through the stabilizing device, a clamping device is arranged on the end wall of the square frame, and the clamping device includes a gear cavity arranged in the square frame, which can realize the movement through the device, thereby clamping the damper, and the clamping is relatively firm and will not be loose, so as to prevent the damper from being misplaced or shifted, causing the failure of the shock-absorbing connection; the movement through the device can realize the stabilization of the damper, improve and ensure the shock-absorbing connection effect of the damper. Although the above-mentioned installation structure can better install the damper, ensure the shock-absorbing protection effect of the damper, and will not be misplaced or shifted, causing the failure of the damper, the device is relatively large in size, and is only designed to stabilize the tool during installation, and there is no design for fine adjustment during installation.

[0007] It can be seen from the above disclosed installation forms of seismic dampers that although the current technology can complete the installation and fixing operations of seismic dampers, their installation methods each have obvious defects. Either they cannot be adjusted during installation, resulting in low installation accuracy, or the installation is complicated or restricted, resulting in low installation efficiency.

The walking wheels 12 are universal wheels, and there are four of them, which are respectively arranged at the four corners of the bottom frame and distributed in a rectangular shape. The top rod is connected to the top ends of the two vertical support rods 13 and is parallel to the transverse frame rods 111.

[0038] like Figure 1 , Figure 2 and Figure 3As shown, the lifting device includes a lifting frame 2, a support frame 3 and a hoisting mechanism 4. The lifting frame 2 includes a lifting support rod 21 extending in the horizontal left-right direction. The lifting support rod 21 is a U-shaped rod, and its two vertical rod sections extend into two lifting slide grooves 131 respectively, and are adapted to the size of the lifting slide grooves 131 to prevent the lifting support rod 21 from being displaced in the horizontal front-back direction during lifting.

[0041] like Figure 3 As shown, each load-bearing fork 311 is equipped with a longitudinal fine-tuning mechanism 32. Figure 5 As shown, the longitudinal fine-adjustment mechanism 32 includes a longitudinal adjustment bolt 321 threadedly connected to the vertical connecting plate of the load-bearing fork 311 and a movable plate 322 slidably assembled on the horizontal long strip of the load-bearing fork 311 in the front-to-back direction. The axis of the longitudinal adjustment bolt 321 extends in the front-to-back direction, and the rear end of the longitudinal adjustment bolt 321 is rotatably assembled with the front end of the movable plate 322 through a bearing. When the longitudinal adjustment bolt 321 is screwed, the longitudinal adjustment bolt 321 pushes the movable plate 322 to move in the front-to-back direction.

[0042] like Figure 3 As shown, each movable plate 322 is provided with two height fine-adjusting mechanisms 33 spaced apart from each other. Figure 6As shown, the height fine-adjustment mechanism 33 includes a height adjustment bolt 332, a bearing plate 331 and a guide rod 333. The bearing plate 331 is located above the movable plate 322 and is flush with the movable plate 322. Two guide rods 333 are arranged in parallel and at intervals. The guide rods 333 pass through the bearing fork 311 and the movable plate 322 and are connected to the bottom of the bearing plate 331. The height adjustment bolt 332 passes through the bearing fork 311 and the movable plate 322 and is rotatably assembled with the bearing plate 331 through a bearing. The height adjustment bolt 332 is threadedly connected with the movable plate 322. The horizontal long strip of the bearing fork 311 is provided with an avoidance groove that is guided and matched with the guide rod 333 and the height adjustment bolt 332. The bearing plate 331 is used to support the anti-seismic damper. By rotating the height adjustment bolt 332, the vertical position of the bearing plate 331 can be adjusted, thereby adjusting the height of the anti-seismic damper. By rotating the longitudinal adjustment bolt 321 , the position of the bearing plate 331 in the front-rear direction can be adjusted, thereby adjusting the position of the anti-seismic damper in the front-rear direction.

[0043] like Figure 3 and Figure 4 As shown, a transverse fine-tuning mechanism 5 is provided between the load-bearing connecting rod 312 and the lifting support rod 21. The transverse fine-tuning mechanism 5 is a gear 52-rack 51 mechanism, including a gear 52 and a rack 51 meshing with each other, wherein the gear 52 is rotatably assembled with the lifting support rod 21 through two vertical rods, and the rack 51 extends in the left-right direction and is fixedly connected to the load-bearing connecting rod 312; the rack 51 and the load-bearing connecting rod 312 are integrally located in the installation cavity of the lifting support rod 21, and an opening is provided on the top cavity wall of the installation cavity, and the gear 52 partially crosses the opening and meshes with the rack 51. The axial direction of the gear 52 extends forward and backward, and a handle 53 is connected to the gear 52. When the handle 53 is turned, the gear 52 rotates, driving the rack 51 to move left and right, thereby driving the entire support frame 3 to move left and right to adjust the left and right position of the anti-seismic damper.

[0044] The anti-seismic damper installed in the present invention is a shear-type metal damper. The anti-seismic damper installation auxiliary device of the present invention can also be applied to the installation of other types of anti-seismic dampers, such as friction dampers.

[0045] The use process of the anti-seismic damper installation auxiliary device of the present invention is as follows: The seismic damper to be installed is placed on the bottom frame, and the construction personnel push the walking frame 1 to transfer the seismic damper to the installation position, and the lifting support rod 21 is lowered to the position of the bottom frame by the hand hoist 43, and the seismic damper is placed on the load-bearing plate 331, and then the seismic damper is lifted between the upper embedded steel plate and the lower embedded steel plate by the hand hoist 43 again; the lifting process is a rough adjustment process of the height, during which other seismic dampers on the bottom frame can be used as counterweights to ensure the stability and safety of the lifting; after being in place, the walking wheel 12 is locked to ensure that the entire installation auxiliary device will not move during the installation process; observe whether the top surface of the seismic damper is consistent with the upper embedded steel plate, and whether the bottom surface is consistent with the lower embedded steel plate, and use a five-line green light level to correct the verticality of the vertical long side of the seismic damper. If the verticality is not achieved, adjust it by rotating the height adjustment bolt 332 in the height fine-tuning mechanism 33 to make its verticality meet the requirements; after the verticality meets the requirements, use a ruler The lateral position of the seismic damper is determined by measuring until the lateral position of the seismic damper is centered between the upper embedded steel plate and the lower embedded steel plate. In this process, the handle 53 is rotated to drive the rack 51 to move to complete the lateral adjustment. After the lateral adjustment is in place, the longitudinal position of the seismic damper is determined by measuring with a ruler until the longitudinal position of the seismic damper is centered between the upper embedded steel plate and the lower embedded steel plate. In this process, the longitudinal adjustment bolt 321 in the longitudinal fine-tuning mechanism 32 is rotated to adjust the front and rear position of the movable plate 322. After adjustment, observe Check whether the top and bottom surfaces of the seismic damper are centered and fitted with the upper and lower embedded steel plates respectively. If there is still deviation, repeat the above fine-tuning steps and repeat them repeatedly until the seismic damper reaches the installation position. Lock all the adjustment mechanisms and then weld the seismic damper to the upper and lower embedded steel plates. Use arc welding with welding wire to spot weld the four corners of the damper and the upper embedded parts first, and then weld along the four sides of the damper one by one. Clean the welding slag after welding.

[0046] After the installation is completed, the height adjustment bolt 332 is reversed to release the height lock; the longitudinal adjustment bolt 321 is reversed to release the longitudinal lock; the hand crank hoist 43 is pulled to lower the entire support frame, and the support plate or placement box is removed; the lock of the walking wheel 12 is released, and the installation auxiliary device is withdrawn, and the anti-seismic damper installation process is completed; then the walking frame 1 can be pushed to the installation position of the next anti-seismic damper.

[0047] The present invention saves installation time of the anti-seismic damper, and a single person can complete the installation work, thereby improving the installation efficiency. The position of the anti-seismic damper can be accurately adjusted through various fine-tuning mechanisms to ensure the installation accuracy of the anti-seismic damper. In addition, after installing an anti-seismic damper, the present invention can directly push the walking frame 1 to move to the next installation position without the need for individual transportation, thereby further improving the installation efficiency. The present invention has a simple structure, simple operation, and low requirements on the professional level of workers.

[0048] In other embodiments, the vertical support rods, lifting frames and load-bearing forks may also be made of steel sections, and the slide grooves on the steel sections may be used to adjust and guide the positions of the corresponding components, thereby avoiding the need to provide slide grooves on the corresponding components.

[0049] In other embodiments, the lateral fine-tuning mechanism can also adopt a screw-nut transmission mechanism, in which a lateral adjustment screw is rotatably installed inside the lifting support rod, one end of the lateral adjustment screw is provided with a first bevel gear coaxially connected thereto, a second bevel gear rotatably installed inside the lifting support rod and meshing with the first bevel gear, a handle extending out of the lifting support rod is connected to the second bevel gear; the two load-bearing forks are respectively connected to a lateral slider threadedly connected to the screw, and by rotating the handle, the first bevel gear is driven to rotate, thereby driving the lateral adjustment screw to rotate, and when the lateral adjustment screw rotates, the lateral slider is driven to move, thereby realizing the left and right movement of the support frame.

[0050] Similarly, in other embodiments, the longitudinal fine-tuning mechanism may also adopt a screw-nut transmission mechanism, in which a longitudinal adjustment screw is rotatably mounted on the load-bearing fork, and a guide column parallel to the longitudinal adjustment screw is provided, a hand wheel is provided at the end of the longitudinal adjustment screw away from the lifting support rod, and a longitudinal slider threadedly connected to the longitudinal adjustment screw is connected to the bottom of the movable plate, and the longitudinal slider passes through the guide column and can slide relative to the guide column.
